This deck is an attempt to make Savage Incursion work in straight Hooru.
Since we're not a mill deck, the other way to make the opponent send cards to their void is to kill their units. This deck is chock full of ways to do that. The strategy is stall and survive while filling the opponent's void.
A couple of cards of note:
Lys, Champion of Linrei - If used carefully, can discard a ton of useful cards from the enemy hand. Using this when your opponent is power-screwed is not a good idea. It has the backup function of cycling your hand if you have a hand full of power or similar. Can still be killed by fast spells at end of turn before effect triggers, so playing when opponent is tapped out is helpful sometimes.
Kenna, Shaman of the Scale - Recursion for Savage Incursion if all goes well, though I could see replacing this with
Prodigious Sorcery although there aren't a lot of targets for it in this deck. The killer effect is quite useful for adding versatile removal, and obviously this deck is full of spells so the +2/+2 effect can trigger quite a bit. It's very expensive, too, so I'll need to test further on this.
